摘要

為提高薏苡單位面積產量，於1996年引進9個薏苡品種（系）進行特性觀察，結果發現全農分系具有優良農藝性狀及高生產力，於是利用混合選種法選出87-T6參加1999～2002年新品系比較試驗，由於農藝性狀及產量表現優越，選出定名為臺中選6號，參加2003～2004年新品系區域試驗，並於2003～2005年進行新品系栽培法試驗、品質檢定及抗病蟲檢定，因具有株高較低、耐倒伏、每平方公尺分蘗數較多及稔實率較高、產量高及富含營養成分等特性，於2006年7月7日獲准登記命名為臺中2號並推廣之。

In order to increase the yield of job's-tears in Taiwan, 9 varieties (lines) of job's-tear were introduced during 1996. In observation trials, the variety Chuannong line showed superior agronomic traits and higher productivity to other tested varieties. A line Taichung No. 6 was selected through mass selection procedure and joined new lines comparison trials during 1999-2002. Due to the supreme agronomic performance and yield of this line, it was further put in new lines regional trials during 2003-2004. Cultivation method experiment, quality determination and pest resistant tests were subsequently conducted during 2003-2005. The line shows many supreme agronomic characters including shorter plant height, lodging resistance, higher tiller number per m^2, can be planted in high density, higher percentage of fertility grain, and resulted in higher yield. The grain crude protein, crude fat, crude fiber and ash of this line were higher than the control line Taichung No. 1. The line was approved and registered as Taichung No. 2 in July 7, 2006 and extended to farmers.
